ack in August, my needs were simple. As one of the reporters covering the Redskins for The Post, I needed a television and a way to record games so I could analyze what turned out to be a five-win season. A $119 combination 13-inch TV with a VCR would have solved the problem.

Instead, I ended up taking the high-definition plunge, spending $1,399 for a far-bigger and fancier television set than I originally had in mind. As I left the store with my new HDTV, my confidence was boosted by approving nods from people in the parking lot.

Most new HDTVs have inputs for both types of high-definition cables, but not all video sources - cable or satellite boxes, upconverting DVD players or high-def video game consoles - use the same connections. Both types of cables can sell from $10 to $100, with minimal difference in quality. (Ignore composite and S-Video connections, which can?t carry a high-def signal.)

"It's going to change your life," one man said.

If only someone had told me that buying the set was the easiest part.

Since then, I have been riding a high-definition roller coaster -- mesmerized by the new TV's crystal-clear images but disillusioned by the disappointingly low number of HD channels you get in exchange for the investment of the upgrade.

My purchase put me in a growing wave of people switching to high definition. Last year, more than 13 million HDTV sets were shipped to stores in the United States, and the Consumer Electronics Association predicts that even more -- closer to 16 million -- will hit shelves this year.

Moving into HDTV had been on my mind for a while. I'd been admiring a 50-inch plasma, and its dropping price tag, for about a year, but I was still fighting the psychological barrier of paying such big money for a TV. I'd spent less than $300 on a 27-inch Toshiba tube set only four years ago and wasn't mentally ready to shell out four figures for a replacement.

And so, faced with the onset of the season and needing a second set at home, I headed out with self-restraint and intentions of saving money by going low-tech -- until I started comparing prices and saw how much they had come down.

A 27-inch tube set is the same price today as the one I bought four years ago, around $275, but a Polaroid 20-inch flat-panel, HD television was less than $50 more, at $318. A 32-inch combination TV-VCR cost in the mid-$300s, but a Samsung 32-inch HD was in the low $600s, which didn't seem unreasonable considering the quality of the picture.
